The manufacturer reference Mersen Q220952 could not be matched to a reliable public Mersen product page, technical datasheet or catalogue listing. The precise product family, catalogue number, electrical ratings, dimensions and connection arrangement therefore cannot be confirmed accurately from publicly available information.
To avoid publishing incorrect or potentially unsafe technical data, the Q220952 should be checked against the original product label, packaging, supplier documentation or an official Mersen datasheet before a complete product description is created.
The reference is similar to part numbers used within Mersen’s industrial fuse ranges, but this similarity is not sufficient to identify the product or determine whether it is a semiconductor fuse, railway fuse, replacement component or another electrical product.
Check the product body and packaging for a second reference containing letters and electrical values, such as a catalogue number, series designation, current rating or voltage rating. These details are normally required to distinguish between products that may have similar manufacturer references but different operating characteristics.
Any proposed replacement should be compared with the original component’s complete electrical and mechanical specification. The current rating, voltage rating, utilisation class, breaking capacity, dimensions, fixing centres and terminal arrangement must all be suitable for the equipment and application.

The exact product associated with Mersen reference Q220952 could not be verified from reliable publicly available manufacturer information.
This cannot be confirmed without an official Mersen catalogue entry, datasheet or additional product number identifying the series and operating class.
A direct replacement should not be assumed until its current rating, voltage rating, operating characteristics, dimensions and terminal arrangement have been confirmed against the original component.
A photograph of the product label, its full catalogue number, current and voltage markings, series name and physical dimensions will normally provide the information required for accurate identification.
Estimated electrical specifications could lead to the selection of an unsuitable component and create risks for equipment reliability and electrical safety.
Do not select or install the Mersen Q220952 solely by visual appearance or a partial reference. Confirm the complete manufacturer specification before purchase, substitution or installation.
